STENT-WITHIN-STENT ARRANGEMENTS

机译:帐房-帐房安排

摘要

A variety of stent arrangements are described in which multiple stents expand and coordinate to block the spaces between the struts of the outer stent to create a tubular stent not prone to tissue in-growth. One or more stents are selectively positioned within an outer stent such that the struts of the one or more stents at least partially fill the openings of the outer stent. Alternatively, the one or more stents may be permanently affixed to the outer stent to produce a stent arrangement in which the openings between the struts of the outer stent are blocked by the struts of the one or more stents.
